LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented. Nov. 17, 1908.

Application filed August 29, 1906. Serial N 0. 332,463.

To all whom it may concern:

Be it known that I, RAYMOND M. HAVENS, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Loose Leaf Binders, of which the following is a specification.

This invention relates to loose leaf binders and has for its object to produce a simple, strong, durable, cheap and efficient device of the character named.

With this purpose in view the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood ref erence is to be had to the accompanying drawings, in which Figure 1, is a perspective view of the binder, and also shows a package of the sheets or leaves to be filed between the lids and the means for holding the same in position. Fig. 2, is a top plan view of the same partly broken away. Fig. 3, is a section taken on the line AA of Fig. 2. Fig. 4, is a detail perspective view of the standard-carrying plate forming a part of the invention. Fig. 5, is a top plan view of one of a pair of slides shown in Fig. 1. Fig. 6, is a perspective view of the slide-operating disk. Fig. 7, is a perspective view of the disk-carrying plate forming part of the invention.

Referring to the drawings, in detail, 1 indicates the binder, comprising a bottom plate 2, and a top plate 3, the former hav ing a pair of rigid vertical standards 4 and 5. The top plate 3 is provided with V-shaped recesses 6 and 7 in its free ends and with three perforations 8, 9, and 10. Pivotally mounted 011 the upper end of screw 12 secured in plate 3, is a disk 11 provided with a stem or handle 13 and a thumb piece 14 for convenience in manipulation.

Bigidly secured to the top plate and extending through perforations 8 and 10 are pins 15 and 16 provided with collars 17 and 18 as seen in Fig. 3. Pivotally connected to said disk 11 by rivets 21 and 22 are slides 19 and 20 bifurcated at their outer ends, said bifurcations being approximately V-shape as shown at 23 and 24, and these bifurcations are adapted to receive the vertical standards 4 and 5 and to bear with l I l 1 increasing frictional pressure on the opposite sides of the latter as they are forced outward by the manipulation of disk 11.

The lids or covers of my loose leaf binder are made of any suitable material, 25 indicating the bottom cover and 26 the top cover, the latter being provided with a flex ble port-i011 27 to permit the top lid to be raised for convenient reference to the sheets or leaves of paper filed on the standards and identified by the number 23.

Before the papers leaves or sheets are filed they must be perforated with a suitable punch, to correspond with the size of the standards t and 5 and the distance between the standards.

In practice when it is desired to file papers 011 the standards the handle of the disk is forced to the position shown in dotted lines Fig. 2, this movement simultaneously moving the slides until their outer ends are d1sengaged from the standards so that the lid can be readily removed.

After filing the sheets or leaves the lid is replaced in its original position with the recesses 6 and 7 in the plate 3 engaging the standards and then the lever is forced to the position shown in Fig. l to resecure the upper lid in operative position.

From the above description it will be apparent that I have produced a loose leaf binder possessing the advantages enumerated and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown as obvious modifications will suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire to secure by Letters Patent, is

In a loose leaf binder, a lower lid provided with rigid vertical standards, 4, 5, to receive perforated sheets of paper, an upper lid having a plate with notches in its rear edge to engage said standards, a pair of pins 15, 16 between the standards, riveted to the notched plate and projecting upward therefrom and headed at their upper ends, and provided below and spaced from said heads with collars 18, 17 respectively, a screw 12 secured to the plate midway be tween and in line with said pins and standards, a disk 11 pivoted on said screw and provided with a handle 13 extending radially of the disk and occupying the same horizontal plane and provided at its outer end with an upwardly projecting thumb-piece 14, and a pair of slides 19 and 20 pivoted at their inner ends to and at the upper side of the disk at diametrically opposite points and at opposite sides of the longitudinal center of handle 13 and provided in their outer ends with longitudinal bifurcations approximately V-shaped in plan and engaging the guide pins and the standards.

Intestimony whereof I aflix my signature, in the presence of two Witnesses.
